I hope people realize how much effort it takes to play this game of court, especially from Aira's position.
Commoner origin, daughter of a prostitute, taken in by the head of the house.
In original timeline, no formal upbringing, no training, no education.
Current timeline; bare minimum but she's still behind Mielle who's been taught since birth.
Mielle who is the first legal daughter, has the backing of all the servants (remember Jessie had to be won over), even the coachman who helped tried to injure Aria, her father the head of house, and her brother the heir to the house.
Aria is surrounded by enemies, trying to create her own allies as much as possible, playing mind games with Mielle and the men around her (what is seduction but mind games?), her only advantages being the hourglass and rough memories of the original timeline, and even that is shaved away by the hourglass's restrictions and how the current timeline changed. Because she knows if she messes up and doesn't get the better of Mielle, her mother gets poisoned and somewhere down the line, her head ends up on the chopping block.
